Application filed January 18, 1915. Serial No. 72,774.

To all whom it may concern Be it known that I, LOUIS G. LARsEN, a

citizen of Copenhagen, Denmark, and a resisigned for talking machines, and more particularly to devices of this character wherein the rotation of the rotating element or turntable is made to stop when the traveling element or tonearm ceases its movement across the same.

The objects of the present invention are to provide a simple, economical and etlicient device of this character which may be readily installed, which will ediciently perform its stopping function wnen the tone-arm comes to rest, however long or short the sound-record may be, and which is so simple in construction and operation as to minimize the chances of the parts ofthe device becoming deranged and failing to operate.

The inventive idea is applicable without regard to the particular character of motor en'iplcyed for rotating the turn-table. For the purpose of illustrating the invention, it is shown in connection with a brake mechanism which is applied to stop the turn-table when the tone-arm movement across the sound-record ceases. But the invention is equally applicable to a construction in which an electrical motor, for example, is employed for rotating the turn-table, and in whichmeans, as for example an eiectrical switch, is operated to effect the stopping of the motor.

The invention will be better understood by reference to the accompanying drawings, illustrating one expression of the inventive idea, and wherein- Fig. 1 is a side elevation of atalking ma: chine provided with the improved device;

Fig. 2 is a top plan view, partly broken away to show the mechanism beneath the motor-board I Fig. 3 is an inverted plan view correspondino; to Fig. 2;

l 1 is a vertical section through the tonearm support, showing the connection between the tone-arm and the stop mechanism;

matic stop mechanism; and

Fig. 6 is a drawn-out perspective view. Referring to the drawings, wherein like reference numerals designate like parts,10 is I .55 Fig. 5 is a perspective view of the autothe usual or any suitable motor-board through which projects a spindle 11 on which is mounted a rotating element or turn-table 12 carrying a sound-record 13, said motorboard being carried by any suitable casing or support. J

The spindle 11 projects through the top plate 14 of a casting in which is mounted any suitable motor, such as a spring motor 2 15, which may be wound in theusual manner by a handle 16. The spindle is rotated from the motor 15 through any suitable connections. As here shown a gear 16 on the' motor shaft drives apinlon 17 on a countershaft 18 through suitable gear connections, I I and a bevel gear 19 on the counter-shaft 18 meshes with a bevel gear 20 (Fig. 3) on the lower end of the spindle 11. This spindle has also mounted thereon, in the form shown,

worm-gear 21 (Fig. which meshes with a worm 22 on a governor-shaft 23 carrying the usual governor balls 24, and alsohaving l mounted thereon a brake disk 25 withwhich are associated the usual or any suitable brak ing pads26. These pads may be moved into and out of engagement with the brake disk 25 to control the speed of rotation of the turn-table by an arm 27 (Fig; 2) associated with a scale 28, said arm being suitably connected to a pivoted lever 291(Fig.

3) on which is mounted the arm 30 carrying the brake pads 26.

The motor-board 10 is shownprovided with a perforated ear'31 on which is mounted a hollow support 32 for the tone-arm or travelling element'33, carrying atone end the usual sound-box 34, provided with a needle 35 that engages the'record groove in the disk 13, by which engagement the tonearm is fed across the sound-record in, a manner well understood in the art."

Secured to the tone-arm 33 and'extending downwardly through the support 32, in the form shown, is'a tubular member 36 to which is frictionally securedin any suitable manner an arm 37. As here illustrated, this arm is provided at one end with an eye or open ing through which the tubular member 36 passes; and annular felt washers 3S and 39 contact on either side with the arm 37 adjacent said opening'(Fig. 4).. These felt washers are held in place by metallic washers 40 and 41, the latter being provided with lugs 42 that engage in recesses 43 in the tubular member 36, whereby washer 41 is locked to said tubular member by a bayonetjoint connection. A spiral spring 44 engages around the tubular member 36, one end of said spring engaging washer 40 and the other end a washer 45, said washers and spring being housed in a recess 46 provided in said support 32.

The free end of said arm 37 is shown provided with a downwardly projecting finger 47 that engages in a bifurcated extremity 48 of an oscillatory lever 49 pivoted at 50 in a bracket member 51 carried by an angle-piece 52 secured to the casting 14 in any suitable manner, as by screws 53 (Fig. 4) It will be observed that, as the travelling element or tone-arm is fed across the record in a clockwise direction, the arm 37 will move in the same direction, and the right-hand end of the lever 49, as seen in Fig. 5, will be moved anti-clockwise as far as it can go, the action of the tone-arm tending to maintain the arm in this position. The movement of the lever 49 toward the right is limited by suitable means carried by an oscillatory member or arm 54 which is pivoted on a screw 55 carried by the angle, iece 52. This pivoted member or carr ing arm 54 is moved or vibrated to and fro in any suitable manner. As here shown, said arm is provided with an offset or hooked extremity 56 which engages a cam 5'? mounted on a stub-shaft 58 carried by the casting 14, said cam being associated and movable with a gear 59 in mesh with a pinion surface 60 on the spindle 11. This cam acts to move the pivoted'member 54 in one direction; and a spring 61, one end of which is connected to 7 said member and the other end of which is anchored to the casting 14, is preferably en ployed to return the pivoted member or arm to its original position.

The particular means here shown which limits the movement of the right-hand end of the pivoted lever 49 under the influence of the travelling element or tone-arm is a lug 61 carried by the pivoted'member 54 and, during the reproduction of the soundrecord, the lever 49 continually contacts with said lug, so that said lever is positively but intermittently moved in one direction by and with the pivoted member 54, and is moved intermittently in the opposite direc tion, and held against the lug 6.1, by the operation of the moving tone-arm.

Upon the cessation of movement of the tone-arm, the pivoted member 54 moves the lever 49 into engagement with the means, wnether mechanical or electrical, that effect the stopping of the turn-table. As here shown, the means are mechanical and embody a brake that operates on the brake disk 25.

The particular embodiment shown of this aspect of the inventive idea is best illustrated in Figs. 2, 5 and 6. As there shown, an arm 62 which, for convenience, is herein designated as a contact arm, is pivoted on the screw 55 below the member 54, a washer 63 surrounding said pivot being interposed between the members 54 and 69, and a washer 64 being interposed between the contact member 653 and the angle-piece 52. The free end 62 of this contact lever is moved toward the right (Figs. 2 and 5) by a spring 65 one end of which is secured to the extremity 62, and the other end of which is anchored to the top 14 of the motor casting; and, during reproduction of the sound-record, the end of this lever engages in an annular groove 66 just below the head 67 of a braking member 68, and holds said member out of engagement with the brake disk 25. l Vhen said extremity is removed from the groove, the brake ,member 68 is pressed down under the action of the spring 84, the lower end thereof then engaging the periphery of the brake disk 25 (as shown in dotted lines in Fig. 1) and stopping themachine.

Any suitable means are carried by the pivoted member 54 for engaging the lever 49 with the contact member 62 for the purpose of removing the free end 62 of said contact member from the groove 66 to stop the machine and as here shown these means consist of a pivoted trip or latch 69 mounted in lugs 70 and 71 formed integrally with the member 54. This trip or latch is provided with a downwardly projecting nose 72 which, when the tone-arm and the lever 49 .have ceased to move, engages a slot 73 in lever 49 by gravital action whereby the right-hand end of said lever is subsequently moved into engagement with apart oi the contact member 62, moving its extremity 62 out of groove 66 on the brake member 68. In order to compensate for wear, and to secure exact and effective adjustment of the members, the part of the cont-act member 62 engaged by the arm 49 is shown as an inde pendent slotted angle-piece which is pro vided with an upwa. .y projecting portion 7 4 with which the end of the lever 49 contacts, said angle-piece being adjustable toward and from said lever 49 by means at a screw and slot connection, the screws being carried by the member 62 and the slot 7 6 being pro vided in said angle-piece.

Immediately after the lever 49 has disleased the brake 68, astop 77 mounted on the casting 14 engages a downwardly pro jecting tail 78 carried by the trip or latch 69 and rocks the nose 72 of said latch out of engagement with the notch 73, whereupon said nose falls into engagement with the top surface of the lever 49, where it remains until a new reproduction has been effected and the tone-arm and the lever 49 have come to rest, at which time it will again engage slot 7 3 and move the lever 49 to perform again its stopping function. In order to insure the proper vertical positioning of the end 62 of the contact member so that it will engage groove 66 in the brakemember 68 when the latter has been elevated, a pin 79 is carried by the casting 14 and is positioned immediately below the extremity 62. i

If desired, the automatic stop mechanism described may be associated with automatic start mechanism; that is to say, with mechanism associated with the tone-arm such that, when the latter is moved into position at the commencement of the record, the rotation of the turntable will be automatically effected. The start mechanism herein shown is, however, of the manual type, and means are provided for elevating the brakemember 68 out of engagement with the disk 25 so that the turn-table will'commence rotating. As here shown (Figs. 1 and 2), said means consist of a lever 80 pivoted at 81 to the underside of the motor-board 10, this lever carrying at one end a pin 82 that proiects upwardly through an opening in the motor-board. A button or head 83 can ried by said pin for depressing the near end of said lever and elevating the far end thereof. The far end of said lever carries a leaf spring 84 one end of which is fixedly secured to said lever, andthe other end of which en gages the underside of the motor-board 10, the tendency of this spring being to force downward that end of the lever associated with the brake member 68. This lever 80 engages said brake member 68 in any suitable manner, as here shown the extremity thereof engaging in groove 66 in which the extremity 62 of the contact member 62 also engages when the brake member 68 has been elevated. -.t will be understood that the elevation of the brake member 68 is effected by simply pressing on the head or button 83.

The operation of the device is-as follows:

lVhen reproduction is being effected, the parts are in the position shown in 'Fig. 2, the latch 69 being out of engagement with slot 78. The cam 57 rotates with gear 59 and moves the pivoted member or carrying arm 54 in one direction. The lug 61 on said member engages the edge of lever 49 and forces said lever to participate in the movement of member 54, notwithstanding the ac tion of. the moving I tone-arm tenr-ling to move the lever 49 in the opposite direction. The member 54 is moved by spring 61 in a.

direction opposite to that of its movement by the cam 57 as soon as the cutaway portion of the cam is presented to the member 54; and the action of the moving tone-arm on the lever 49 holds it in engagement with lug 61 at this time. The member 54 and lever 49 continue to move back and forthas a unitso long as the tone-arm continues to move across the record but, when the latter stops, the tendency of the toneearm to move the lever 49 against the lug 61 and away from the latch 69 is removed, and said lever nolonger follows member 54 in its anticlockwise movement. The pivoted member 54, however, being driven from the motor, continues to move and, as soonas the cutaway portion. of the cam presents itself to member? 54, the spring 61 moves said member 54 and latch 69 toward the now-stationary lever 49, whereupon the nose 7 2 of latch 69 drops into slot-73. Thereafter the lever 49 is moved toward the part 74 of contact member 62 by cam 57 acting through pivoted member 54, the contact member is displaced, and brake member 68 engages brake disk 25 and stops the rotation ofthe turntable. Practically coincident with the dropping of the brake member the latch 69 is rocked out of the slot 7 3 whereupon, as soon as the brake member 68 iselevated' by lever 80, so that the extremity 62 ofcontact member 62 can engage groove 66 to hold the brake member away from the brake disk, spring 65 then moving member 62 and, through member 74, lever 49 to withdraw slot 73 from under the'nose of latch 69, the parts are again in position for the operation of the automatic stop mechanism.
